rk3128 添加自己的硬件服务后系统无法启动

arvin

我写了一个 driver, 完成相应的HAL，添加JNI方法，并为android app提供相应service,  烧录后系统无法启动，报错 ：Abort message: 'art/runtime/jni_internal.cc:769] JNI FatalError called: RegisterNatives failed for 'com/android/server/Et6296Service'; aborting...'
Et6296Service这个是我的要添加的service.
还忘各位给分析下我问题可能出在了那里，谢谢。

有那位帮忙解答一下吗  谢谢

问题已解，是jni方法里的函数返回值类型与service里面的api返回值类型不匹配造成的。
